BY V a W ATTORNEE Patented May 2t), 1941 UNITED STATES FATE QFEF'EQE 3 Claims.

My invention relates to a new and useful improvement in a templet adapted for use on profiling and reproducing machines in Which the cutting tool or other work piece is guided by a guide or control spindle caused to travel over the contact surface of the templet. In the construction of templets of this class, I have developed a type of templet which is considerably reduced in weight over those heretofore used and which comprise a shell-like body which may be termed concave on one side and convex on the other, either surface being used as the contact surface. I prefer to form these templet bodies from plastic material which will harden after it has been molded to shape.

The present invention is particularly adaptable for use for such bodiesalthough from the de-- scription it will appear obvious that the invention will lend itself to templet bodies formed from another type of material in use-it is customary to attach these bodies to a suitable supported position adjacent the machine with which used.

It is an object of the present invention to provide a templet body of this class so constructed and arranged that means may be easily and quickly mounted thereon which will serve as attachment means for mounting the templet body on the supporting mechanism.

Another object of the present invention is the provision of a templet body of this class having attachment members embedded therein to serve as a means for securing the templet body to a supportin structure.

Another object of the invention is the provision of a templet body of this class which may be simple in structure, economical in manufacture, durable, light, compact, and highly efficient in use.

Other objects will appear hereinafter.

For the purposes of clarity, there is included with the specification a set of drawings in which Fig. l is a side elevational view of the invention,

Fig. 2 is a bottom plan view with parts broken away,

Fig. 3 is a sectional view taken on line 3--3 of Fig. 1.

As shown in the drawing the invention comprises a templet body '5 which is formed of shelllike formation with the convex surface 8 and the concave surface 9. Extending along one portion of the body is a planar surface I0, although in some structures this planar formation might not be present. Embedded into the body I adjacent the surface Ill is a bar I l formed from wood or other suitable material for receiving attachprongs l2, which are embedded in the body 1. In the usual formation, these bars II are positioned opposite each other and are connected by cross rails 13, the ends i l of which project beyond the outer faces of the bars H to attach a means for engaging clamps or other fastening apparatus for securin the structure to the supporting body which is present adjacent profiling or reproducing machine.

By embedding the bars I I in the manner indicated, undue displacement of these bars rela tively to the body 1 is prevented and excessive wear and tear on the bars II is obviated. With the bars ll securely fastened in position, the end rails l4 may be located at any desirable position longitudinally thereof so as to accommodate the structure for adaptation for supporting means and fastening mechanisms of various sizes and types.

By forming the body 1 concave, a durable structure is provided while at the same time lightness is attained.

While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise details shown, but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.

What I claim as new is:

1. A profiling machine templet of the class described comprising: a templet body having a contact surface and provided with spaced-apart planar surfaces; carrying means embedded in i said planar surfaces and having their outer faces ment means. This bar ll carries the anchor projecting outwardly beyond said planar surface; means for anchoring said carrying means on said body; and. attachment means connected to and connecting said carrying means.

2. A profiling machine templet of the class described comprising: a shell-like templet body having a contact surface, and elongated carrying means embedded in oppositely disposed edges of said body with one of the longitudinal faces of said carrying means projecting outwardly from the surface of the edge in which embedded and its opposite face embedded in said body.

3. A profiling machine templet of the class described comprising: a shell-like templet body having a contact surface, and elongated carrying means embedded in oppositely disposed edges of said body with one of the longitudinal faces of said carrying means projecting outwardly from the surface of the edge in which embedded and its opposite face embedded in said body, and an attachment means mounted on said carrying means and connecting together oppositely disposed carrying means.
